A number of puzzles concerning how truth-ascriptions are grounded have recently been discovered by several theorists, following Fine (2010). Most previous commentators on these puzzles have taken them to shed light on the theory of ground. In this paper, I argue that they also shed light on the theory of truth. In particular, I argue that the notion of ground can be deployed to clearly articulate one strand of deflationary thinking about truth, according to which truth is "metaphysically lightweight.'' I will propose a ground-theoretic explication of the (entirely bearable) lightness of truth, and then show how this broadly deflationary view yields a novel solution to the puzzles concerning how truth is grounded. So, if the proposal I sketch is on target, the theory of truth and the theory of ground interact fruitfully: we can apply the notion of ground to offer a clear explication of the deflationist claim that truth is "metaphysically lightweight'' that both captures the motivations for that claim and solves the puzzles.
